Quantrill, 24, was the eighth overall pick in the 2016 draft and commanded top-100 leaguewide prospect billing entering the 2017 and 2018 campaigns. His rise up the rankings stalled out after a suboptimal ’18 effort, though there’s still plenty of reason to hope he’ll be a quality MLB hurler.
This promotion represents a continuation of the Friars’ strategy for managing their bevy of unproven young talent and designs on contention. Quantrill may only be up briefly to begin — the five members of the existing rotation are expected to continue working in a starting capacity — but could be called upon several times throughout the year to help spread innings around. It’s certainly also possible that he could command more opportunities in the majors based upon his own showing.
Quantrill has still yet to master the upper minors, which is likely why he was bypassed when the San Diego organization brought up a series of other young pitchers this year. He’s now carrying a 4.68 ERA in 25 innings over five starts on the year at Triple-A, though that comes with a solid combination of 8.6 K/9 against 2.9 BB/9 along with a 48.6% groundball rate. Quantrill should be ready for a full workload after reaching 148 innings in 2018.
In the event that Quantrill is able to command an active roster spot for the rest of the season, he could accrue as many as 152 days of service. That’d be enough to set him up for future Super Two qualification but not enough to reach a full year of service (which requires 172 days). The club will need to add Quantrill to the 40-man roster before activating him.
